“This OP-1 is in good overall condition and mostly functional, but has some issues:

1) The volume knob does not change the volume. Current volume is set at a useable level but cannot be changed. Volume pot feels wobbly but does turn correctly.

2) Three of the keyboard keys plus the “6” key are not responsive. See photo 11 for a shot of the unit with these four keys removed.

3) Power switch feels sluggish but does work fine every time.

All other controls have great feel and respond accurately. All lights and screen fully functional. All ports and jacks in great shape and connect without issue. Sound is strong and clear from all inputs and outputs. Battery is charging well and holding a charge. No issues mounting the unit as a removable disc on a computer via the USB cable.

The unit passed all practical tests and self-tests with the exceptions of the faults listed above. It has been updated to the most recent 225 operating system.

Sale includes the unit with its original USB cable.

This is being sold as-is, for parts or not working, with no returns. ”

“Up for auction is a Teenage Engineering OP-1 keyboard with a non OEM power adapter. Everything works except the volume knob, which is
is stuck at half the volume. I got this this instrument like this and it really hasn’t been much of a problem for me, but you can buy the replacement board for about $50 on average (here on eBay or elsewhere on the internet, such as iFixit). Note: the volume knob can be physically moved, but it doesn’t alter the sound. All other knobs and buttons work fine.” Click here to search for synths on eBay

“I’m selling my “like-new” OP-1 which features multiple synth engines (including a sampler), effects, various note sequencers and a built in 4-track recorder. I’m selling the unit because I rarely use it anymore. While I love the sounds and build quality, the OP-1 is better suited to more modern and experimental music.

This unit comes with its original hard case (including the original rubber bands intended to keep the case closed once opened), original translucent overlay showing what all the buttons do, original USB charging /connection cable as well as a new soft case that can hold the OP-1 keyboard and the USB charging/connection cable.”

“So you want one of these slick OP-1 synthesizers. But if you’re shopping for such a unique machine, you probably want the full experience that it can offer, as I did. The only problem is, the folks over at Teenage Engineering sell the accessories required to use certain features of the machine separately, and to be frank, the retail price of these accessories are too high to justify buying them new.

I bit the bullet and ordered most of these accessories anyway, as well as many other accessories that are useful for using the OP-1. Let my loss be your gain, and get them for cheap here, included with this listing.” Click here to search for synths on eBay
